Liberators: Orders of Battle
Royalist Regulars
The following Royalist battalions in "Liberators!" and the supplement were Spanish regulars (John Fletcher on Liberators Discussion Forum) :
- Talavera (Rancagua, Chacabuco)
- Burgos (Cancha Rayada, Maipo)
- Gerona (Torata, Moquegua) - this was a light infantry battalion
- Cantabria (Lima, Ica, Torata, Moquegua)
- Imperial Alejandro (Ica)
The following unit was nominally Spanish but 2/3rds of its effectives were Americans or Patriot prisoners:
- Infante Don Carlos (Cancha Rayada, Maipo)
By the time the Infante appear at Lima and Ica I suspect it was almost entirely American.
Pezuela's OB leading to the Battle of Maipo
John Fletcher cited this order of battle and his associated thinking on the Liberators Forum For Free.
Osorio's Division:
Infante Don Carlos Battalion: 983
1st Burgos Battalion: 856
Arequipa Battalion: 899
Volante Artillery: 112
Zapadores: 81
Lanceros del Rey: 193
Dragones de Arequipa: 198
Ordonez's Division:
Valdivia Battalion: 136
Concepcion Battalion: 807
Artillery: 219
Dragones de la Frontera: 316
Dragones de Chillan: 86
"Reunion of various units": 147
Total: 5033
So there's the magic 5000, straight from the memoirs of the Viceroy of Peru.
However, let's subtract the following, who stayed in garrison at Talcahuano:
Valdivia: 136
Artillery: 219
Various Units: 147
Zapadores: 81
Total Garrison: 583
Total Remaining 4451
Subtract the 200 lost at Cancha Rayada and you're at 4251. If you consider that
the book OB does not show the number of artillerists, only the number of guns,
you can take another 112 from Pezuela's 4251, leaving 4139, not far from the
4188 I show in the book OB. If anything, my OB starts to look generous,
especially if we had a sense of the number of desertions and stragglers in the
Royalist ranks.
The one area of the book OB where you could really do some tweaking are the
combined cazadore and grenadier battalions. I basically extrapolated these
numbers and one could easily bring these down to around 450-500 and assign the
remainder among the various infantry battalions.
